Hey guys. I have procomp 4inch full leafs with 1inch drop shackle , iron rock offroad 4 1/2"front coils with 5/8s isolator. I had 31s on it and recently i got 33s. They rub when turning and the back rub at flexing. I dont wana cut the fenders but how much should i go up to clear the 33s for less rubbing? I have a tcase drop with an extended yoke on the driveshaft. I will be getting a hackntap sye shortly abd a CAD. My control arms arent stock but arent adjustable. I wana do an add a leaf in back and replace my coils but im not sure what size il need. Il post a pic on lunch.
